I started watching a series on one of the cable channels called 'First Wave' .....it was a sci-fi show wherein the hero was trying to find out about an alien conspiracy on Earth ...... basically he was engaged in a detective role
I probably only watched the first 10 episodes .... it was OK and I'll watch it again some time (these shows tend to run on a loop on cable channels) ..... I think it was just that something else was starting I wanted to watch and I don't like to commit to more than one of these shows at a time if they're daily episodes
I notice you haven't got 'Warehouse 13' on your list ....... it's set in the same universe as Eureka (with some characters making guest appearances in the other show)
Must say of all the 90s and 00s shows I've been catching up on I thought W13 was the best ! ........ it's a couple of FBI agents who are seconded to a secret organisation to investigate events connected to ancient artefacts and collect such artefacts for safe keeping in the Warehouse..... it's a rollicking good show with terrific characters. I'm certainly going to watch it again sometime.
